Software Differences Mew
a. FLOAT/BOOST/EQUALIZE DCV is based upon 2.265 (volts per cell).
FLOAT DCV = 2.265 X
FLOAT
= 544 Vdc 240 cells (40 batteries).
FLOAT DCV = 530 Vdc 234 cells (39
FLOAT DCV = 5 16 Vdc 228 cells (38 temporary RM only).
b. Battery Overvoltage occurs at 15 Vdc above Float, which stops the
(30 second time delay).
DC occurs at 700 Vdc (preset), which stops the (3 sec. time delay).
d. DC (Inverter stops, load to bypass if available) accomplished via any one of
three factors:

(three) times the Battery Autonomy (as in Level 1).
3. 390 Vdc is the absolute minimum. as the Inverter cannot operate properly below value.
e. Also note that is and the Inverter has shut down due to DC UV, and the
Battery CB is closed; will be tripped 2 (two) hours.
The Approaching End Voltage value is selectable (which provides a dry alarm contact) in
PERSONALIZATION MENU, Level set at 420 Vdc.
g. Battery CB trips during DIAGNOSTICS, PERSONALIZATION and COMMUNICATION
to prevent a defective Inverter using the battery.
h. DC reading is in whole numbers, and is forced to 0 ADC if
i. ON command is memorized and implemented unless an abnormal is
An automatic restart occurs within 30
seconds in normal alarm conditions.

a. OUTPUT FREQUENCY reading is forced to 60.0 if+/- 0.1 Hz.
Two Inverter CURRENT LIMIT faults within 30 seconds disable restart.

d. Fan causes an as an automatic transfer to Static Bypass (tier a 30 second time
delay), otherwise the is in danger of overheating.
e. Inverter ON command is memorized a&implemented an abnormal alarm is present.
An automatic restart occurs 30 seconds normal alarm conditions.
PERSONALIZATION Level 2, contains an extra item: OPT.

Note the alarm will be retained in the ALARM MENU.
